+
+# @json-render/svelte
+
+Svelte 5 components, providers, and helpers for rendering json-render specs.
+
+## Installation
+
+<PackageInstall packages="@json-render/core @json-render/svelte" />
+
+Peer dependencies: `svelte ^5.0.0` and `zod ^4.0.0`.
+
+<PackageInstall packages="svelte zod" />
+
+## Components
+
+### Renderer
+
+```svelte
+<Renderer
+  spec={spec}       // Spec | null
+  registry={registry}
+  loading={false}
+/>
+```
+
+Renders a spec with your component registry. If `spec` is `null`, it renders nothing.
+
+### JsonUIProvider
+
+Convenience wrapper around `StateProvider`, `VisibilityProvider`, `ValidationProvider`, and `ActionProvider`.
+
+```svelte
+<JsonUIProvider
+  initialState={{}}
+  handlers={handlers}
+  validationFunctions={validationFunctions}
+>
+  <Renderer {spec} {registry} />
+</JsonUIProvider>
+```
+
+## defineRegistry
+
+Create a typed component registry and action handlers from a catalog.
+
+```typescript
+import { defineRegistry } from "@json-render/svelte";
+
+const { registry, handlers, executeAction } = defineRegistry(catalog, {
+  components: {
+    Card,
+    Button,
+  },
+  actions: {
+    submit: async (params, setState, state) => {
+      // custom action logic
+    },
+  },
+});
+```
+
+`handlers` is designed for `JsonUIProvider`/`ActionProvider`. `executeAction` is an imperative helper.
+
+## Component Props
+
+Registry components receive `BaseComponentProps<TProps>`:
+
+```typescript
+interface BaseComponentProps<TProps> {
+  props: TProps;
+  children?: Snippet;
+  emit: (event: string) => void;
+  bindings?: Record<string, string>;
+  loading?: boolean;
+}
+```
+
+Use `emit("eventName")` to trigger handlers declared in the spec `on` bindings.
+
+## Context Helpers
+
+Use these helpers inside Svelte components:
+
+- `getStateValue(path)` - read/write state via `.current`
+- `getBoundProp(() => value, () => bindingPath)` - write back resolved `$bindState` / `$bindItem` values
+- `isVisible(condition)` - evaluate visibility via `.current`
+- `getAction(name)` - read a registered action handler via `.current`
+- `getFieldValidation(ctx, path, config)` - get field validation state + actions
+
+For advanced usage, access full contexts:
+
+- `getStateContext()`
+- `getActionContext()`
+- `getVisibilityContext()`
+- `getValidationContext()`
+- `getOptionalValidationContext()`
+
+## Streaming
+
+### createUIStream
+
+```typescript
+const stream = createUIStream({
+  api: "/api/generate-ui",
+  onComplete: (spec) => console.log(spec),
+});
+
+await stream.send("Create a login form");
+
+console.log(stream.spec);
+console.log(stream.isStreaming);
+```
+
+### createChatUI
+
+```typescript
+const chat = createChatUI({ api: "/api/chat-ui" });
+await chat.send("Build a settings panel");
+console.log(chat.messages, chat.isStreaming);
+```
+
+## Schema Export
+
+Use `schema` from `@json-render/svelte` when defining catalogs for Svelte specs.

+
+Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```sh
+# create a new project
+npx sv create my-app
+```
+
+To recreate this project with the same configuration:
+
+```sh
+# recreate this project
+npx sv create --template minimal --types ts --no-install svelte-chat
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```sh
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```sh
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.

+const AGENT_INSTRUCTIONS = `You are a knowledgeable assistant that helps users explore data and learn about any topic. You look up real-time information, build visual dashboards, and create rich educational content.
+
+WORKFLOW:
+1. Call the appropriate tools to gather relevant data. Use webSearch for general topics not covered by specialized tools.
+2. Respond with a brief, conversational summary of what you found.
+3. Then output the JSONL UI spec wrapped in a \`\`\`spec fence to render a rich visual experience.
+
+RULES:
+- Always call tools FIRST to get real data. Never make up data.
+- Embed the fetched data directly in /state paths so components can reference it.
+- Use Card components to group related information.
+- NEVER nest a Card inside another Card. If you need sub-sections inside a Card, use Stack, Separator, Heading, or Accordion instead.
+- Use Grid for multi-column layouts.
+- Use Metric for key numeric values (temperature, stars, price, etc.).
+- Use Table for lists of items (stories, forecasts, languages, etc.).
+- Use BarChart or LineChart for numeric trends and time-series data.
+- Use PieChart for compositional/proportional data (market share, breakdowns, distributions).
+- Use Tabs when showing multiple categories of data side by side.
+- Use Badge for status indicators.
+- Use Callout for key facts, tips, warnings, or important takeaways.
+- Use Accordion to organize detailed sections the user can expand for deeper reading.
+- Use Timeline for historical events, processes, step-by-step explanations, or milestones.
+- When teaching about a topic, combine multiple component types to create a rich, engaging experience.
+
+DATA BINDING:
+- The state model is the single source of truth. Put fetched data in /state, then reference it with { "$state": "/json/pointer" } in any prop.
+- $state works on ANY prop at ANY nesting level. The renderer resolves expressions before components receive props.
+- Scalar binding: "title": { "$state": "/quiz/title" }
+- Array binding: "items": { "$state": "/quiz/questions" } (for Accordion, Timeline, etc.)
+- For Table, BarChart, LineChart, and PieChart, use { "$state": "/path" } on the data prop to bind read-only data from state.
+- Always emit /state patches BEFORE the elements that reference them, so data is available when the UI renders.
+- Always use the { "$state": "/foo" } object syntax for data binding.
+
+INTERACTIVITY:
+- You can use visible, repeat, on.press, and $cond/$then/$else freely.
+- visible: Conditionally show/hide elements based on state. e.g. "visible": { "$state": "/q1/answer", "eq": "a" }
+- repeat: Iterate over state arrays. e.g. "repeat": { "statePath": "/items" }
+- on.press: Trigger actions on button clicks. e.g. "on": { "press": { "action": "setState", "params": { "statePath": "/submitted", "value": true } } }
+- $cond/$then/$else: Conditional prop values. e.g. { "$cond": { "$state": "/correct" }, "$then": "Correct!", "$else": "Try again" }
+
+BUILT-IN ACTIONS (use with on.press):
+- setState: Set a value at a state path. params: { statePath: "/foo", value: "bar" }
+- pushState: Append to an array. params: { statePath: "/items", value: { ... } }
+- removeState: Remove by index. params: { statePath: "/items", index: 0 }
+
+INPUT COMPONENTS:
+- RadioGroup: Renders radio buttons. Writes selected value to statePath automatically.
+- SelectInput: Dropdown select. Writes selected value to statePath automatically.
+- TextInput: Text input field. Writes entered value to statePath automatically.
+- Button: Clickable button. Use on.press to trigger actions.
